IMPROVEMENT IN BILLIARD-TABLB GUSHIONS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHESTER E. WILCOX, of the city and county oi'- Uilwaukee, and State of Wisconsin, have invented a new and useful Improvement in Billiard-Table Cushions; and I do hereby declare that the following is a full, clear, and exactA description thereof, which will enable those skilled in the art to make und use the same, reference being had to the accompanying drawings, forming part of this specification, .in which- Figure 1 is a perspective View. l

Figure 2, a cross-section.

Similar letters of-reference in each of. the figures indicate corresponding parts.

The object of my invention is to make a billiard-table cushion so graduated in elasticity that a bull, when striking it, shall always leave it on an angle corresponding with the angle with which it strikes it, whether the,

blow struck be with greater or less force, and this I do by cutting a. slot in the top'of the cushion, dividing its top into two parts.

A s-the cushion-frame; B, the cushion, made of rubber or other suitable elastic substance. C -is a grooveV or slot, cut in the top longitudinally; D, a. steel spring, embedded in the front of the cushion,

Operation: I'Vhen the ball strikes the cushion, the steel spring D, yielding with the rubber, in which it is embedded byits stiffness, keeps the rubber from being so abruptlyindcnted as it otherwise would be; throws the ball from it in aI truer angle, and with more force than the rubber would alone. A slight blow of the ball bends or springs the forward section of the cushion back to the slot C; but when aI heavy blow is struck, the front cushion is indented or sprung back, closing the slot C and pressing with more or less force against the backv cushion, and its elasticity is then added to that of the front, and adds its force to throw 0H' the ball, thus accomplishing the object sought. v

WhatI claim asrmy invention, and desire to secure by Letters Patent, is-

A billiard-table cushion, when made with slot C in its top, substantially as and for the purpose described.
